Computational Plasma Physicist Intern Summer 2025

About Thea Energy:

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.

Fusion Energy Engineering Intern Program:

We are looking for talented physics interns to join our stellar team for the summer or during the school year!

• Summer 12-16 week internship program and/or flexible school year internship
• For school year internships, expected time dedication is flexible with an hourly rate and tailored to your academic schedule

• Computational physicist projects
• Divertor modeling. Involves modeling of heat flux on plasma facing materials using state of the art computer codes.
• Equilibrium optimization. Optimizing stellarator equilibria using state of the art optimization codes.
• Computational plasma physicist projects
• Fast particle confinement. Studying the confinement of fusion born fast particles in Eos and Helios stellarators.
• Plasma Simulation. Simulating plasma confinement and transport using gyro-kinetic codes.

• Enrolled in a STEM undergraduate or graduate program (physics, mechanical engineering, aerospace engineering, materials science, electrical engineering, etc.)
• Interest in clean and sustainable energy to combat climate change
• Hands-on or computational experience through academic research, club projects, hackathons, or industry internships
• Highly self-motivated, independent, and driven to solve problems
• Authorized to work in the US
